- No run-time dependencies- Designed with developers in mind. You can pick up a stranger and weird library like this one, then use it right away without worrying about it invading your own preferences, or breaking your app's resource names (or other libraries' resource names). Short answer: it uses a UUID for its preference file name, and a CRC-32 string to prefix its resource names (see FAQs: https://bitbucket.org/haibison/android-lockpattern/wiki/FAQs ).- Designed for both phones and tablets- Stealth mode (invisible pattern)- Many built-in themes: + Dark/Light + Light with dark action bar (available from API 7+, but only works from API 14+) + Dark/Light dialogs + Dark/Light DialogWhenLarge (available from API 7+, but only works from API 11+)- Ability to generate and let the user verify CAPTCHA pattern

* Currently the app is not available in some countries. We are sorry for the inconvenience.

The app needs some more permissions to help us monetize it. With this service we are able to create more great apps and libraries for you guys.

Thanks. And yes you can, absolutely. The library is released under Apache License v2.0 (http://www.apache.org/licenses/LICENSE-2.0). You can also use the library in your commercial or closed source apps :-)
